4K@120Hz HDMI 2.1 Switch 2 in 1 Out with Audio Extractor VRR ALLM HDCP2.3 ARC eARC HDR CEC SPDlF Optical Audio Out D-o-l-b-y Digital EDID for PS5 Xbox NVIDIA AMD

I’ve been using the REI HDA-931 for extracting 7.1 Atmos for use with my Sonos Arc soundbar for a couple of years now—both with an older Panasonic plasma TV and now an XGIMI Halo+ projector (by way of an HDMI transmitter. The issues with the REI include intermittent HDMI handshakes with the Sonos, and a flaky Micro USB connection at the back. I was on my 3rd box when I tried this “EZCOO” option. Worked right away and with full 7.1. The DC connection is much more secure (screws on). Of course time will tell, but save for the lack of mounting holes at the back (I’m using gaffer tape) it’s better than the REI in every way.

Everything works right with minimal setup. 4k/60hz Dolby vision to the projector and Dolby Atmos to the receiver worked perfectly. However, no matter what configuration I set the switches to, HDMI-CEC for power and for volume would not work; CEC would send to the projector for volume depending on the configuration, but would never send to the receiver. CEC Power on/off signals never propagated. My setup does not use CEC Input switching so I do not have any results of it. My verdict is great product if your specific setup does not use CEC.

My TV was driving me nuts with a pass through audio delay (Apple TV —> TV —> Sonos Arc soundbar). I tried using an HDFury Arcana to split the audio and video into separate signals, but it’s a complicated (and expensive) device that I couldn’t figure out how to work. This was a plug and play solution. My only complaint is that the CEC functionality isn’t 100%. It works for on/off functions for my TV through the Apple TV, but not volume up/down functions to the Sonos Arc.

Initially it helped me fixed the audio sync issue between my tv and soundbar. Unfortunately after about six months I stopped having audio coming from my center channel when connecting. After a hard reset I got the center channel back but lost my surround channels. Nothing I did brought the sound back from the surround channels so I ended up plugging directly in to my sound bar again. It’s a cool idea but a $100 product shouldn’t die after six months.

Using this with PS5 to 4k 130hz monitor and Creative G8 DAC. One of few devices I've found so far that'll let me for this all via HDMI.For the most part it works great, but when Frames drop below about 90 I get bad screen tearing. I'm going to order another and see if the issue continues.

This device would have solved all my problems. It came close, see below.The Good: Sounds good after break in. No loss of picture/sound with HDMI extraction. When set to match EDID of TV, it syncs well enough (some cutout of sound when using 4k 7.1 setting on my setup). The device switches well; dual inputs, yea!The Bad: I got this to fix an issue with my Samsung s90c (assume this is a problem with all Samsung TVs) where I can't use it for eARC without it messing up the back surround channels in LPCM (fine with Dolby Audio). This device duplicated the SAME PROBLEM, where the back channels are barely heard in LPCM 5.1 surround. I tried switching modes, but no mode has fixed the problem. Still investigating, but will have to return the item soon. I have the feeling it's a hardware limitation. Yes, I DO have audio extractors that don't have this problem; they just don't have dual inputs.

No problems so far. No cutout.

Perfect - exactly what I needed.ATMOS passthrough - Check.ATMOS extract to 2nd HDMI - Check.Dolby Vision passthrough - Check.120hz passthrough - Check.Remote control switching - Check.Not tested:VRR.Digital audio out.eARC.The device does everything I needed to the highest standard. There was no loss in quality from the full-signal passthrough, nor the audio-extraction. I perceived no lag with video signal pass through. I perceived effectively 0 lag with the audio extraction pass through (run through a secondary receiver).The unit is well built, metal, and doesn't get hot. The HDMI ports feel tight and secure - no play, no cables getting loose.This product solves 2 problems for me: it addresses an issue with my TV's HDMI ports (only 1 port seems to work at a time), and the need to connect a subwoofer to a "closed system" wireless soundbar. I had expected I would need 2 different products to do this - so this was a great find.Regarding audio lag: a subwoofer being slightly delayed compared to the main speakers is not a huge deal. As long as the bass is pretty close to the explosion - the experience is good. However, just as a test I sent the audio extract to a entirely separate AV Receiver and surround sound system.This obviously seems like a bad idea - there is no way for the 2 surround systems to 'talk' to each other, and one would expect echo/delay/bad sound. The result was actually VERY IMPRESSIVE! There was no perceivable delay, and the additional power and frequency response of 2 tower speakers really filled out the presence of the wireless system.The only place where there may be a bit of 'echo' is with the voice channel. I could not hear any delay or echo with the voice, but my SO claimed to. It may have just been the fact that voices were coming from the center channel now (the wireless system has no center channel). In any event, this is something that can be addressed with the AV receiver and I believe achieving a perfect voice sync is possible. If not, the center channel can be disabled.Hooking up a secondary surround system (in the same room) is not likely on anyone's to do list - but with this device it is now possible.I couldn't be happier with this product.
